FRED T. CARPENTER, OF TOLEDO, OHIO.

FLUSH CAR-DOOR.

Specification of Letters Patent.

To all whom it may concern y Be' it known that l, FRED vT. CARPENTER, a citizen of the United States, and a resident of Toledo, in the Icounty of Lucas and State of Ohio, have invented a certain new and useful -Flush Car-Door; and I do hei'eby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and tothe characters of reference 'car side or frame work atall times, whether in open or closed position,'is practical and safe to use and is a `material improvement over doors of the flush type heretofore used.

Further objects and advantages of the invention will be apparent from the following description. v

The invention is fully described in the following specilication, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure l is a side elevation of a portion of a wood frame freight car embodying the invention with the door in closed position. Fig. 2 is a section on the line in Fig. 1. Fig. 3 is a vertical section on the line .0f- 00' in Fig. 2. Fig. 4 is a horizontal section of a side portion of a steel frame car embodyingthe invention with the door in closed po sition. Fig. 5 is a vertical section vthereof on the line iv-w in Fig. 5. Fig. G is an enlargement of a portion of the section fio-cv. Fig. T is an enlargement of a portion of the section -:r in Fig. l, and Fig. 8 is a perspective view of a side-portion of a steel frame freight car with my door in Y ,closedl position.

Referring to the drawings, l designates a side of a wooden type of freight car, la the side of a steel frame type of freight car, and 2 the sliding flush door thereof. ln the case of a wooden frame type of car the This invention relates particularly to front and rear jainb-posts are preferably of wood and are designated 3 and 4, respec-` tively, in Figs. l and 2, while in the case of a steel frame type of car two of the customary external reinforcing posts or members, which are usually of Z-form are employed as the front and rear jamb-posts, and

such posts are designated 3a and 4, respectively, in Figs. 4 and 8. The Z-bar posts vhave their outer ianges extending toward each other to lap and protect the respective side edges of the door when in abutment with such posts. The jamb-posts have their outer sides substantially flushwith the outer car side and the center post 5, which is disposed between the two jamb-posts is spaced inward from the outer side of the car to permit the door to have free sliding movements past the' same. The space between the front jamb-post and the center post 5 is open to provide the door opening, while the space between the rear jamb-post and center post is closed preferably a metallic plate or sheeting 6, which is in-,

wardly spaced from the car si leand has its side edges secured in suitable manner to the posts between which it is disposed.

7 designates the upper side beam of a car and 8 the-lower side beam thereof, which may be of wood, steel or other material, as desired. y

The door is suspended from a track 9 beneathfascia boards 'i'2L on the side beam 7 by roller-brackets 10, and its lower edge slidingly operates over a sill-strip l1, in vertically spaced relation thereto, as best shown in Fig. 3. The sill-strip 11 extends the ent-ire distance between the amb-posts 3 and 4, and'is mounted on the lower side sill 8 in case of a wooden construction of car,

and upon a sill part 8a projecting from the side beam 8 in a. steel frame car. The sillstrip is of angle-bar form in cross-section with its inner flange extending upward. The track 9`is preferably z -bar form in cross-section with its inner Harige' extending upward and bolted or otherwise suitably secured tothe upper side beam 7, and' its outer liange extending downward in posi tion to coact with the upper edge of the door to limit the outward movements thereof relative to the car side and to retain the rollers on thel brackets 10 in contact with the track.

A Z-bar Strip 13 is preferably secured to the lower edge of the door with one flange ltl extending upward at the o'nter side of the door and bolted or otherwise suitably seenrcd thereto, and with the other angre eX- tending.;` drm'nward beneath the door in position to have transverse abutting,r contact with guide-tongues lll, which are carried by the sill-.strip il at the outer side of the lower llanee oi the strip lift, as best shown in It and t3. Yln order that the door may have 'tree ,sliding movements relative to the guidetone'ues ll and at the same time be held closely against; the front jamb-post 3ft, as the case may be, and the center posty 5, when the door is in closed position, to prerent a rattling thereol, the opposite end ptn'tions of the bottom thingie ol the door strip ll are provided with studs or ol'l'zset portions l5 in position to have comming Contact with. the inner side olli' the respective end tongues ll; to eoact therewith when the door is closed to torce the lower edge ot' the door against the registering; stationary portions ot the ear. Tongues lti also projectl from the jamlrposts 3 and Llin position to overlap the respective edges ot" the door when in substantially abuttingl Contact with the respective posts. While it is preferable to make the strip l-'l ol" .-bar form, a strip of other suitable form for eoaoting with the eiiiilotonejues l-t may be substituted therefor. il." desired.

fl? designates a loch-bolt, which is Carried by the door at the lower portion thereo'l.i and is adapted to have its lower end projected into openings in the sill-strip il 'to retain the door in open, partially open or closed positions. jin angle-bar strip 18 is secured to the post. 5 with one flange forming a facing for the side ot the post which is exposed to the door opening and with the other flange lapping the outer side of the post and spaced therefrom at its edge, as shown in Fig. Q. A similar angle-bar strip 19 is secured to the rear edge ot the doo]l with one flange lapping 'the inner side edge thereof in spaced relation thereto to have interlocking engagement with the spaced edge of the strip 18 when the door is closed, whereby to provide a elose joint between the rear edge of the door and post 5 when the door is in closed position, as shown in Fig. 2.

llt will be apparent with my improved construction of door that the saine always stands in tlnsh relation to the car side whether the door is in open or closed position, thus making it impossible to tear the door from the car by side swiping,77 as is so frequently the case with the forms of l'lush doors which stand ont `from the ear sides when the doors are in open position. lty is also erident that all guiding' parts tor the door are set either flush with or wit-hin a plane which is tlnsh with the side ol? a ear to prevent sneh parts liromvbeine struelt and torn 'from the ear by passing trains, or in any other inannern l wish it. understood that my invention is not limited to any specitic construction, i'orm or arrangement of the parts except in so l'ar as such limitations are speeilied in the e l ai in.

Having;v thus described my invention, what l claim as new, and desire to secure by liet- 'ters Patent, is,-

ln a ear, a door casing` comprising` spaced apart front. and rear jamlrposts oit' .T-bar l'orm. with their outer flanges extending' toward each other, said posts being substantially flush with the outer side ol the car, a center postl intermediate said jamh-posts set. inwardly from the outer Vertical plane ol: the jamb-posts, top and bottoni side beams connecting said posts` a closure wall extendingin substantially the plane of the centerpost 'from the center-post. to the rear jambpost, a track carriedv by the upper side beam with its outer edge substantially llush with the outer sides ot the jamb-posts, a door hung from said track flush with the side ot the car to close the space between the 'front and center posts and adapted to slide toward the rear post without said Closure wall, a sill-strip extendingT between the jamhwposts beneath .the door. and Asinide-members rising from said sill-strip within the vertical outer side plane of the jambposts and eoaetine with the lower edge of the door to giiide the sliding' movements of the door.

ln testimony whereof, l have hereunto signed my name to this specification in the presence of two subscribing witnesses.
